The immune system is the part of the body that fights infection and disease.

HIV stands for human immunodeficiency virus. It harms your immune system by destroying a type of white blood cell that helps your body fight infection. This puts you at risk for serious infections and certain cancers.

Explaining HIV and AIDS

HIV is a virus that targets and alters the immune system, increasing the risk and impact of other infections and diseases. Without treatment, the infection might progress to an advanced stage called AIDS. The life expectancy of a person with HIV is now approaching that of someone who tests negative for the virus, provided that the person takes medications called antiretroviral therapy on an ongoing basis. These are types of T cell — white blood cells that circulate, detecting infections throughout the body and faults and anomalies in other cells. HIV targets and infiltrates CD4 cells, using them to create more copies of the virus. This increases the risk and impact of opportunistic infections and some types of cancer. It is worth noting, however, that some people have HIV for long periods without experiencing any symptoms.

HIV Overview

It is also defined by numerous opportunistic infections and cancers that occur in the presence of HIV infection. The virus attacks the immune system and leaves the body vulnerable to a variety of life-threatening illnesses and cancers. Common bacteria, yeast, parasites, and viruses that ordinarily do not cause serious disease in people with fully functional immune systems can cause fatal illnesses in people with AIDS.

Acquired immunodeficiency syndrome AIDS is a chronic, potentially life-threatening condition caused by the human immunodeficiency virus HIV. By damaging your immune system, HIV interferes with your body's ability to fight infection and disease. It can also be spread by contact with infected blood or from mother to child during pregnancy, childbirth or breast-feeding. These drugs have reduced AIDS deaths in many developed nations.
